TIRE-PATCH.

To all whom it may concern:

Be it known that 1, JAMES T. SWINT, a citizen of the United States,residing at Wrens, in the county of Jefferson and State ,of Georgia,have invented certain new and useful Improvements in-Tire-P'atches; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to tire patches and has for its primary object toprovide a tire. patch of efiicient and inexpensiveconstrucsame-size asthe other plate so as to increasethe clamping e'li iciency of the platesupon the tire casing.

With these and other objects in view, the invention consists in thenovel construction, arrangement and formation of parts as will behereinafter specifically described, claimed and illustrated in theaccompanying drawing, in which:

Figure 1 represents a' sectional view through a fragment of a pneumatictire illustrating the improved patch applied to use.

Fig. 2 represents a plan view of the inside of the outer clamping plate.

Fig. 3 represents a plan view of the inner clamping plate removed, and

Fig. 4 represents an end elevation of the clamping bolt removed.

Referring to the drawing in detail, wherein similar reference numeralsdesignate cor responding parts throughout the several views, the numeral5 indicates the inner clamping plate which is curved conformably withthe inner surface of a pneumatic tire casing 6 and is formed with acentral aperture 7 having a plurality of radiating recesses 8 in theedge thereof which are beveled and adapted to receive the spurs 9 formedSpecification of Letters Patent.

at one end of the bolt shank 10 to lock the Patented Feb. 11, 1919'.

Application filed June 25, 1915. Serial No. 36,261.

formed with a central aperture 12 adapted to receive the free end of thebolt shank 10. A nut 13 is fitted upon the bolt 10 and is adapted to beadvanced against-the outer clamping plate 11 to move the latterinwardlyinto clamping engagement with the tire 6, as clearly illustratedin Fig. 1.

The inner surface of the outer plate 11 is formed with a substantiallyoval shaped depression or' cavity 14 having inclined walls 14 snuglyreceiving the plate 5, which latteris formed with rounded ends and edgesdesigned to firmly clamp the tire casing without creasing, cutting orotherwise injuring the latter. The rounded edges and ends. of the-plate5 further insure against injury to the inner tube of the tire whichengages therewith.

lVhile I have here shown the tire patch of an elongated formation andshaped to fit a tire casing circuxnt'erentially, it will be understoodthat the patch may be made in inner substantially rectangular clampingplate curved longitudinally and having rounded ends, said inner platebeing adapted to snugly fit into said depression and having roundededges adapted to clamp a tire casing against the inclined walls of saiddepression, and means carried bysaid inner clamping plate for securelyclamping the plates together.

In testimony 's'vhereof I aflix my signature in presence of twowitnesses.
